Example: Simplifying and Rewriting Expressions
Use symbolic keywords combine and rewrite to combine and rewrite expressions.
Keyword: simplify
• Simplify the following expressions:
• Insert the symbolic evaluation operator.
• Insert the keyword simplify in the placeholder.
Keyword: combine
• Use the keyword combine to combine the following expression:
 | The keyword combine does not affect the result. |
• Add the modifier sincos to specify rewriting the result in terms of sine or cosine.
• Use the keyword combine with other modifiers to combine more expressions.
Keyword: rewrite
• Use the keyword rewrite to rewrite the following expression using specific types of identities:
PTC Mathcad returns an error because rewrite requires a modifier.
• Add the modifier exp.
PTC Mathcad rewrites sin in terms of exponential functions.
• Use the keyword rewrite with other modifiers to get the desired type of result.
